Sleeper hit "A Letter to Grandma (给阿嬷的情书)" decryption key extended to June 30; Douban (豆瓣) rating rises to 9.2

Extension and ratings

It has been reported that the digital decryption key for the surprise box‑office hit A Letter to Grandma (给阿嬷的情书) has been extended until June 30, allowing the film to remain available for online playback on platforms that rely on time‑limited DRM keys. At the same time, the film’s score on Douban (豆瓣) — China’s leading film‑review platform, roughly analogous to IMDb mixed with Rotten Tomatoes — ticked up from 9.1 to 9.2, a rare climb for a wide‑release feature.

Story and box office

The film follows Chaozhou grandmother Ye Shurou (叶淑柔, played by 吴少卿) and her grandson Xiaowei (晓伟, 郑润奇), who travels to Thailand searching for a rumored tycoon only to return with a family‑shattering revelation: the man his grandmother had been exchanging love letters with was not who she thought. The movie opened on April 30 and, against low expectations, reportedly crossed the 1 billion yuan mark at the mainland box office by May 24.

Why this matters

Why does a decryption‑key extension matter? In China’s digital ecosystem, distributors control playback windows through DRM keys; an extension signals confidence from rights holders and preserves momentum on streaming platforms and ticketing channels. For Western readers: China’s domestic box office remains the dominant battleground for local filmmakers, especially as import quotas and broader geopolitical frictions constrain the flow of foreign films. Can the film sustain word‑of‑mouth through the extended window and translate acclaim into longer‑term streaming revenue? The extended key gives it the chance to find out.
